I recognized a serious problem in ReplaceFramesMC script

[gil900]

Hello,
One of the posts I got this script:

AviSource("step 1 - filtered.avi")
Crop(8,0,-16,-16)


function ReplaceFramesMC(clip Source, int N, int X)
{
    # N is number of the 1st frame in Source that needs replacing. 
    # X is total number of frames to replace
    #e.g. RX(101, 5) would replace 101,102,103,104,105 , by using 100 and 106 as reference points for mflowfps interpolation
 
    start=Source.trim(N-1,-1) #one good frame before, used for interpolation reference point
    end=Source.trim(N+X,-1) #one good frame after, used for interpolation reference point
 
    start+end
    AssumeFPS(1) #temporarily FPS=1 to use mflowfps
  
    super = MSuper()
    backward_vec = MAnalyse(super, isb = true)
    forward_vec = MAnalyse(super, isb = false)
    MFlowFps(super, backward_vec, forward_vec, blend=false, num=X+1, den=1) #num=X+1
    AssumeFPS(FrameRate(Source)) #return back to normal source framerate for joining
    Trim(1, framecount-1) #trim ends, leaving replacement frames
  
    Source.trim(0,-N) ++ last ++ Source.trim(N+X+1,0)
}

# deinterlace it
Bob()

# replace frames



# reinterlace the video
AssumeTFF()
SeparateFields()
SelectEvery(4,0,3)
Weave()

I use it to repair damaged frames...

But I always got the result image is not as sharp as I like ..
I thought it was the tape ..

But now, I checked to see if it is the script that dameg the sharpness of the video.

The result is surprising.

So here is two pictures of the same frame of the video.

Photo One is when the script runs (code above) :



And the second image with this code: (no ReplaceFramesMC)

AviSource("step 1 - filtered.avi")
Crop(8,0,-16,-16)

There is a big difference in sharpness if you check out the pictures one by one.

It's not really bad if you bring me a new code of ReplaceFramesMC Which does not affect sharpness of the video.
In that case I'll just have to process what I did again But with a new code and the same settings..

I do not need to re-create the lists.. But it is still bad to my computer (it will have to work overtime)

Thanks for helpers ..


EDIT:

Ok sanlyn,
Now I understand why you write this:

Import("C:\Program Files (x86)\AviSynth 2.5\plugins\QTGMC-3.32.avs")
Import("C:\Program Files (x86)\AviSynth 2.5\plugins\DeVCR.avs")
Import("C:\Program Files (x86)\AviSynth 2.5\plugins\stab.avs")

AssumeTFF()
QTGMC(preset="fast")
DeVCR(20)

At the beginning of the code In the example you sent me ..
I thought I was smart ass( = Google Translation) .. I did not understand why i need so i deleted it. (This slows the processing)

So I added just like the example you sent me and now it's fine!

Too bad I understand things too late...

I don't know about replaceframesmc but one script i like to replace frames is dvdropouts (for progressive frames by default) kinda old but give it a try. Requires mvtools-v1.11.4.5

function morph (clip c, int in, int "out", int "blksize")
{

Function fill_loop(string s, int stop, int count)
{
return (stop == 0) ? s : string("tofill.mvflowinter(fill_vb,fill_vf,time=" + string(100*(count - stop)/float(count))) + ",thscd1=255,thscd2=255).selectevery(tofill.framec ount(),0)," + fill_loop(s,stop-1,count)
}

out=default(out, 0)
blksize=default(blksize,16)

d=c.trim(in,out)# in-1?

numframes=d.framecount-2
tofill=d.selectevery(c.framecount(),0,c.framecount ()-1)

fill_vf=tofill.mvanalyse(truemotion=true,blksize=b lksize,pel=2,isb=false,overlap=blksize/2)
fill_vb=tofill.mvanalyse(truemotion=true,blksize=b lksize,pel=2,isb=true,overlap=blksize/2)
filled=eval("interleave(" + fill_loop("" ,d.framecount()-1,d.framecount()-1) + "tofill.selectevery(tofill.framecount(),tofill.fra mecount())).assumefps(c.framerate())")
c.trim(0,in-1)++filled++c.trim(out+1,0)
}

the syntax:
separatefields()
morph(3422,3424) # to replace frames 3423
weave()
